A Bioabsorbable Drug-Eluting Stent: 2-Year Data

Theoretically, an effective bioabsorbable stent would temporarily scaffold the vessel wall, reduce neointima proliferation without increasing the risk for late thrombosis, and restore vascular integrity. Early results of a small, manufacturer-funded, open-label study of a bioabsorbable, polylactic acid stent coated with a more rapidly absorbable, everolimus-eluting polylactic acid layer were promising (JW Cardiol Mar 26 2008). The present report contains the 2-year follow-up results obtained with multislice CT, angiography, intravascular ultrasound, and optical coherence tomography (OCT).

Clinical outcomes were available for 29 of 30 patients with single, de novo coronary lesions treated with 3 mm x 12 mm stents or with 3 mm x 18 mm stents: …
